Throat Pain Causes & When To Consult The Doctor

Overview of Throat Pain

Throat pain, also called pharyngitis, occurs due to inflammation in the throat. It happens when bacteria or viruses enter the pharynx, the tube at the back of our throat, between our voice box and tonsils. The bacteria causes inflammation in the pharynx and makes it red and swollen. It can also cause itchiness and dryness in the throat. People with throat pain have difficulty swallowing food due to infection. Some other bacteria called gonorrhea and chlamydia can also make the pharynx swell up which leads to increased throat pain. Sore throats usually get better in one or two days, but it is best to consult a doctor if you have other symptoms like swollen tonsils or fever.

Causes of Throat Pain

Throat pain mainly occurs due to a bacterial infection in the throat caused by strep throat. The following are some other causes of sore throat:


Allergies in the respiratory system like sinusitis, asthma, and flu can also cause throat pain. People with dust allergies are more likely to have throat pain.


Studies suggest that occasional smoking can cause respiratory problems like sore throat, cough and shortness of breath. The components in cigarette smoke can irritate the throat and cause inflammation. Even if you do not smoke but remain around people who smoke too often, you breathe the smoke passively. It can still cause throat pain.


Tumor in the throat can cause lymph nodes to swell up. It might cause redness, swelling, inflammation, and throat pain.

Inflammation in voice box or tonsils

Sometimes, inflammation in the voice box, called laryngitis, and inflammation in tonsils, called tonsillitis, may increase inflammation in the pharynx.


Having too much spicy food can cause ulcers in the throat or gastrointestinal region. It may lead to inflammation and redness in the throat.

Weak immunity

This is also a common factor for weak immunity as it makes the body prone to infections. People with a weak immune system often get flu or allergies. They are at an increased risk of catching throat infections.

Symptoms of Sore Throat

In most cases, sore throat includes scratchiness, difficulty swallowing, coughing, dryness in the throat, and throat pain. Following are a few commonly symptoms of sore throat:

    • Runny nose
    • Cold and cough

Health Risks Arising due to Sore Throat

Even though a sore throat is not alarming, it can cause health risks in rare cases.

Abscesses in tonsils

Severe throat pain for weeks can cause abscesses around tonsils which form pockets of pus near them.

Ear infection

Sometimes, the bacterial infection in the throat can also spread to the sinus or ear and increase pain.

Rheumatic fever

Strep throat, if not treated timely, can cause rheumatic fever that leads to inflammation in joints.

Drink ginger tea

Ginger tea is another best throat infection home remedy. It also has anti-inflammatory properties that help treat throat infections and reduce itchiness and swelling. You can also add spices like turmeric, black pepper, and cinnamon to ginger tea.

Use a humidifier

Sitting in a room with dry air for a long time can also cause irritation in the throat, as the mucus membranes present in the nose and throat get dry. You can use a humidifier or take steam to increase moisture in your nose and throat.

Drink cold liquids

If you are wondering how to cure a sore throat fast, you can also try drinking cold liquids. While this might seem like an unusual home remedy, drinking cold liquids can help calm inflammation in the throat and reduce pain and swelling.
